红绿灯。。。//手写红绿灯
int yellow = 10;
int red = 3;
int green = 4;

void setup() {
// put your setup code here, to run once:
pinMode(yellow,OUTPUT);
pinMode(red,OUTPUT);
pinMode(green,OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:
int i = 0;
for (i=0;i<5;i++){
    digitalWrite(red,HIGH);
    delay(1000);
}
digitalWrite(red,LOW);
for (i=0;i<2;i++){
    digitalWrite(yellow,HIGH);
    delay(1000);
}
digitalWrite(yellow,LOW);
for (i=0;i<5;i++){
    digitalWrite(green,HIGH);

    digitalWrite(yellow,HIGH);

就4个状态嘛简单粗暴实现

选了一个最简单粗暴的做法实现红绿灯.反正就4个状态嘛，那就直接全局变量状态，然后判断状态值是什么再显示，简单粗暴其实不错，代码不贴了太简单
